Former workout video instructor Leisa Hart tells us how she's using science to create her perfect regime

It's seldom someone finds their life passion at Fifteen years old, but Leisa Hart was lucky enough to stumble-quite gracefully-into her life's work on an early age. Leisa is best referred to as lead trainer for fitness videos such as Buns of Steel, Abs of Steel, Arms of-you get the picture, plus Fit Mamma and other bestsellers. In the last few years, Leisa closed her studio and stopped teaching classes to be able to concentrate on her family and consult for a number of fitness companies in her spare time. We meet up at a neighborhood park in Allen, before we start chatting, Leisa and I work up a sweat. She leads me within an outdoor workout involving yoga, a bit of running and striking some tough poses with exercise bands. Obviously, Leisa definitely has muscles of steel.
